It breaks up to 15 kA per IEC 60947-2 and 5 kA per UL 1077 / CSA C22.2 No. 235 — that 15 kA figure covers most industrial panel fault levels up to the service entrance.
The 63 A rating is at 35 °C; derate to 58.4 A at 40 °C, 55.94 A at 45 °C, 53.36 A at 50 °C, and 50.65 A at 55 °C — useful when the breaker sits in a warm enclosure next to other heat sources. IP20 with conductors connected — standard for enclosed panel mounting.
15 kA per IEC 60947-2 and 5 kA per UL 1077 / CSA C22.2 No. 235.
